Methods for Production of Fatty Acid Alkanolamides (FAAAs) from Microalgae Biomass

Description:

Project ID: D2014-07

IP Status: Provisional patent # 62/095,502 filed

Invention Description: Concise and efficient procedure for FAAA synthesis and isolation from lipid-containing algal biomass.

 

Applications: Industrial uses such as biosurfactants or biolubricants including personal care products, pharmaceuticals, detergents, rust inhibitors, ink formulations; and many other applications.

 

Novelty: Methods of reacting biomass:

1)     Achieves near quantitative conversion of the fatty acyl donors (FAD) in the lipids FAAA or fatty acid alkyl esters (FAAE) or a mixture of FAAA and FAAE;

2)     Recovers the FAAA, FAME, or mixture of FAAA and FAME from the reaction medium; and

3)     Converts any FAAE in the recovered portion also to FAAA by reacting the FAAE in the recovered portion in a second step.

 

Value proposition: Advantages over existing strategies include:

·       Methods described circumvent solvent-based recovery and purification of FAG or FAME prior to conversion to FAAA resulting in fewer unit operations

·       Algal lipids are either directly converted to FAAAs or first converted to FAME, which is recoverable as a separate phase.

·       Methods described use recyclable catalysts and can be operated under mild conditions.

·       Reliably recover > 95% of the total lipid in the biomass.

·       Methods of isolating the product from the reaction mixture.
